Green Synthesis, Characterization, and Antibacterial Activity of Metal Nanoparticles and Nanocomposites Using Leaves Extract of Prunus persica L.

The ZnO, MgO, NiO, and AlO nanoparticles and Zn–Al and Mg–Ni composite oxides were synthesized by the green method from the Prunus persica leaves extract. The synthesized nanoparticles were characterized through FT-IR, XRD, SEM, and TEM. The FT-IR study was carried out to find out the presence of various functional groups in nanoparticles. Their size was studied by the XRD method which exposed that the nanoparticles were in the range of 19–29 nm, and the size and morphology were studied by SEM, which was further confirmed by TEM. The synthesized nanoparticles were tested for antibacterial activity. In particular, ZnO showed a good inhibitory effect with 22.31 mm of inhibition against Pseudomonas aeruginosa.
